Müller et al investigated the physicochemical process of extracellular matrix calcification in both physiological (bone) and pathological (vascular calcification) contexts; they found that oxidative stress-induced poly(ADP-ribose) nucleates calcium phosphatemineral crystals on extracellular matrix substrates and that calcification is inhibited by poly(ADP-ribose) polymerase (PARP) enzyme inhibitors.
